Analysis of Common Faults and Treatment of Compression Granulating Machine
1 Introduction
Compression granulating machine is widely used in chemical industry as an important grain-making device. It has the characteristics of high efficiency, simple structure, convenient operation and maintenance, and low energy consumption. The reason for its widespread use is that it can make various solid and pellet products with granular materials. However, due to its frequent operation, some common faults often occur, which affects its efficiency and user experience. Therefore, analyzing the main causes of these common problems and providing corresponding solutions have become particularly important.
2 Common Faults and Causes
The common faults of the compression granulator are mainly concentrated in the problems of bearing not rotating, material not entering, blockage of material, and so on.
1. Bearing not rotating: The cause of this failure may be due to the lubrication of the bearing being insufficient, and the friction between the bearing and the shaft sleeve makes the bearing cannot rotate. In addition, the bearing with too much backlash or too tight fixing will also cause this failure.
2. Material not entering: This situation occurs when the shape of the material and the shape of the material inlet do not match. Or, the distance between the material inlet and the compression chamber may be too large, making it difficult for the material to enter smoothly.
3. Blockage of material: This situation usually occurs when the material is too dry. When the material to be extruded is too hard, it will also cause blockage. In other words, when the material is damp, it will stick and agglomerate, thus blocking the material.
3 Solutions
The specific solutions to the above common problems are as follows:
1. Bearing not rotating: Check the lubrication condition of the bearing first and add the lubricant when necessary. Secondly, check the tightness and gap of the bearing and adjust it in time.
2. Material not entering: Check the shape of the material to see if it matches the inlet shape. In addition, we can adjust the distance between the material inlet and the compression chamber, so as to ensure that the material can enter the compression chamber smoothly.
3. Blockage of material: Use high-humidity material to reduce the viscosity of the material, which will make it easier to enter the compression chamber. If the material is too dry, you can sprinkle some water on it and let it absorb some water to reduce its degree of dryness.
4 Conclusion
The compression granulator has become increasingly popular in the chemical industry because of its high efficiency, simple structure, and low energy consumption. However, due to the frequent operation and use of this device, some common faults often occur. This article has detailed the main causes of these common problems and provided the corresponding solutions. It is hoped that this article will bring some help to the users of industrial compression granulators.
